Rainbow Solar Inc. (RSi) recently announced the world’s first, transparent, photovoltaic-glass window that generates 80 to 250 watts of electrical power, while saving up to 50% on heating and cooling requirements too.

This is the first production BIPV (building integrated photovoltaic) product of its kind, an enclosed super tempered glass window system, with a patent pending, fully integrated, multi-tier photovoltaic and heat insulation technology. Current production lines are capable of producing window sizes up to 9’ x 9’ (2.74m x 2.74m) with comprehensive options, such as fire and bullet proofing, to meet design, weather, climate, and building code requirements.

The RSi PV-Glass Window uses sunlight to generate electricity, reduce heat, and provide a semi-transparent window that allows for privacy, while maintaining a comfortable level of visibility to the outside world. At the same time, RSi PV-Glass Windows provide a 100% reduction in Ultraviolet and Infrared radiation, adding an extra level of protection not offered by standard glass windows.

RSi embedded many smart home technologies into the complete window system, including an optional built-in electrical privacy curtain, to completely block out an already shaded glass window, and a new technology that converts the entire window into a light panel.

RSi’s vision is of buildings that harvest their own energy from unlimited renewable sources. What the company ultimately proposes to do is to eliminate the need for electrical power plants, as well as the grid infrastructure so that the building itself becomes truly autonomous and fully sustainable in terms of electrical power.

Since one of the biggest heat losses from a home is through a glass window, it looks like RSi has a winning combination, stopping heat loss on cold days and keeping heat out on hot days, while generating electricity at the same time. Let’s hope the opaque windows also stop birds flying into windows and then the only remaining technical challenge is implementing self-cleaning windows.
